HEATING-DRUM.

SPECIFICATION forming part of Letters Patent No. 483,116, datedSeptember 20, 1892.

Application filed March 30, 1892- Serial No. 427.001. (N0 model.)

To all whom it may concern.-

Be it known that I, SOLOMON M. KEMP, a citizen of the United States,residing at Baltimore city, in the State of Maryland, have inventedcertain new and useful Improvements in Heating-Drums, of which thefollowing is a specification.

This invention relates to an improved heating-drum for utilizing theheat produced by an ordinary burner-such as a lamp, gasburner, or theliketo warm a room.

With this object in viewthe invention consists in the novel features ofconstruction and combination of parts hereinafter described.

The invention is illustrated in the accompanying drawings, wherein-Figure 1 shows a front elevation of the complete apparatus; Fig. 2; avertical section thereof; Fig. 3, a horizontal section on line 3 3 ofFig. 1; Fig. 4, abottom view of the drum cap or cover.

A curved plate Astands on a suitable base B and is provided with a topcover 0, having a central circularopening a and an upwardextendingflange b about the same. This plate A constitutes an open-front shell orcasing for containing the burner, which in the present instance is alamp D of the wellknown central-draft type and stands on the base B. Theshell A has a horizontal partition E, with a slot D to receive the neckof the lamp, and a slide Fworks in guide-strips F, secured at oppositesides of said slot. This slide fits around the outer side of thelampneck and serves to hold the lamp steady. The partition and slidedivide the lower part of the casing, which contains the globe of thelamp, from the upper part, containing the burner. A series of openings 0in the lower part of the case insure an ample supply of air to keep thelampglobe cool, and another series of openings (1 above the partition Esupply air to the burner. A hood d is secured on the outer side of thecasing, just above thelatter series of openings, and serves to directthe fresh air at the bottom of the room into the openings. A cylindricaldrum G is mounted on the top of the casing A, and its bottom has aninternal conical cap H, which fits over the flange b. A coiled pipe Ileads out of this conical cap to the top parts of the drum, where itpoints toward the front, and the drum has a line of openings .2 at thefront opposite the mouthf of this coil. A cover J is fitted to the topof the drum, and an inclined deflector-plate K is fastened in this coverwith its lower part at the rear of the same and its highest part at thefront. This plate appears as a false cover for the drum. A number ofpipes L open into the lower part of the drum and extend downward on theoutside of the casing A to the lower part of the same, where they haveflared mouths g. These pipes are perforated throughout their length, theperforations h being made in four sides, as shown. The drum and pipesare removable from the case A, and each pipe is held at its lower endbetween staples i on the casing by a hasp j, which takes around the pipeand is hinged in one staple and hooks into the other, as seen in Figs. 1and 3.

The operation is as follows: Whatever heat and light radiates from theburner laterally is thrown outward by the plate A, which thus serves asa reflector. It is therefore given a parabolic curve, as seen in Fig. 3.The greatest heat of the burner and the products of combustion therewithpass directly upward into the conical cap H and thence through the coilI and exit therefrom at the mouth f. The heat which radiates from thecoil during the passage of the products of combustion therethrough heatsthe air contained in the drum. This heated air, together with that whichemanates from the mouth of the coil, issues through the openings 6 intothe room. At the same time the colder air near the floor passes upthrough the pipes L, entering the same through the flared mouths g andperforations h, and supplies the drum with air to be heated and in turnsupplied to the room. The inclined plate K serves to defleet the heatedair in the drum toward the exit-openings a. By my arrangement aroom 5 ofaverage size may be thoroughly warmed and kept at a comfortabletemperature with an ordinary lamp, gas-burner, or similar heatproducingdevice. It will be found very useful in bath-rooms and similar places,which [OS are not usually provided with heaters.

It is evident the construction here shown may be varied without,departing from the spirit and scope of the invention.

Having thus described my invontion, what I claim as new, and desire tosecure by Letters Patent, is

1. The combination of a suitable casing or shell for containing aburner,a drum located above the burner and having an inlet for air atthe lower part and an outlet-opening at the upper part, and a coil inthe drum, having its lower end open and over the burner and its upperend open and within the drum and directed toward the outlet-opening inthe latter.

2. The combination of a suitable casing or shell for containing aburner, a drum located above the same and containing a coil having itsinlet end over the burner and its outlet at the upper part of the drum,the latter provided with an inlet for air at the lower part and anoutlet at the upper part, a cover fitting the top of the drum, and adeflector-plate in said cover.

3. The combination of a suitable casing or shell for containing aburner, a drum located above the same and containing a coil having itsinlet end over the burner and its outlet at the upper part of the drum,the latter provided with an outlet for air at the upper part, andperforated pipes opening into the lower part of the drum and extendingdownward therefrom and open at the lower ends.

4. The combination of a suitable casing or shell for containing aburner,a drum located above the same and containing a coil having its inlet endover the burner and its outlet at the upper part of the drum, the latterprovided with an outlet for air at the upper part, perforated pipesopening into the lower part of the drum and extending downward adjacentto the exterior of the casing or shell and open at their lower ends, andhinged hasps on the said casing and arranged to take around andhold thepipes, in the manner described.

In testimony whereof I aflix my signature in the presence of twowitnesses.

SOLOMON M. KEMP.
